Cognitive Diagnosis Computerized Adaptive Testing (CD-CAT) for Adolescent Internet Gaming Disorder: A Conceptual...

Area of Science:

• Clinical Psychology
• Psychometrics
• Behavioral Health

Background:

• Internet Gaming Disorder (IGD) is a growing concern in adolescents.
• Current assessment tools for IGD are limited in capturing symptom complexity and clinical interpretability.

Purpose of the Study:

• To summarize progress in understanding adolescent IGD and its assessment.
• To propose a novel assessment framework for precise evaluation of adolescent IGD.

Main Methods:

• Compared DSM-5 TR and ICD-11 criteria for IGD.
• Reviewed Classical Test Theory (CTT), Item Response Theory (IRT), and Cognitive Diagnostic Models (CDMs).
• Proposed the Cognitive Diagnosis Computerized Adaptive Testing (CD-CAT) framework integrating CDMs with adaptive testing.

Main Results:

• DSM-5 TR criteria are well-suited for developing distinct diagnostic attributes.
• Traditional methods (CTT, IRT) have limitations in assessing multidimensional IGD symptoms.
• The proposed CD-CAT framework utilizes a Q-matrix based on DSM-5 TR criteria for efficient symptom classification.

Conclusions:

• The CD-CAT framework offers a theoretically grounded approach for advancing precision assessment of adolescent IGD.
• This conceptual model aims to improve clinical relevance and reduce assessment item requirements.
• Further empirical research is needed to validate the proposed CD-CAT system.
